WHY S SERIES?
Click to find more about why the coffee professionals around the world
are so hyped about the S Series
-
S Series is an all-electric roaster.
Ease of Installation
Accurate and precise heat control
Product safety
-
Ease of Installation
Gas powered machines require more
regulatory compliances due to safety
concerns, which makes them much more
difficult and complex to install in-shop.
With S Series, simply plug and play. -
Accurate and precise heat control
Precise and predictable heat control is
the key to consistent high quality roasting.
With dial controls of existing gas roasters,
micro heat adjustment is impossible
because dial levels are seldom proportional
to the actual gas input.
Digitally controlled heat application of the
S Series allows precise control over each heat
source, enabling the user to develop and
explore a wider range of coffee flavors. -
Product Safety
No need to worry about fire or other risks
that gas run devices can cause.
Electricity is not only more convenient,
it is much safer than gas to operate in any
indoor environment.
Triple Heat System
S Series is the world’s first roaster that adopts all three types of heat sources.
1. Convection
Hot air circulates throughout the drum and penetrates every bean for uniform heat distribution. Stronghold uses Swiss made Leister heater and blower for maximum heat efficiency and powerful diffusion.
2. Conduction
Surface temperature of the tower drum is reconfigured to accurately match preset temperature, preventing burning of bean surface during consecutive roasting.
Beans are spread out against the drum surface by the rotating stirring wings inside the drum. The vertical drum’s innovative design ensures uniform transfer of heat from the drum surface to the beans.
3. Radiation
Radiation heat emitted from the halogen lamps directly penetrates the beans and allows uniform heating even at the core. Hence, a perfectly roasted, never burned, and very flavorful coffee bean that is celebrated by not only professional roasters but also by our customers who are new to roasting.
Customers do not become loyal to a coffee shop that “sometimes” has great coffee. Simply put, consistency is key to building a strong brand. What if you could save all your roast profiles and precisely replicate them whenever, wherever, and by whoever with just a touch of a button? Well, NOW YOU CAN, with the S Series. Using PID principle, our proprietary heat control algorithm makes micro level heat adjustments to immediately react to any divergence from the saved roast profile, replicating your favorite roast with consistency beyond human capabilities.
Go spend more time with your customers or your loved ones, work on new menus, finish your paperwork, do what you gotta do that makes you happy. Let the S Series take care of the roasting part of your life.
S SERIES Technology
Stronghold’s patented vertical drum technology optimized for electric roasters,
Tower Drum
-
"For an idea or a product to become innovative, it has to first break with tradition."
The “vertical” Tower Drum is designed to harness all the advantages of using an electric heat source and it is the heart of the S Series that integrates the most advanced roasting technologies. -
Optimal Heat Efficiency
Conventional electric roasters before the S Series faced the challenge of reducing heat loss on horizontally placed drum roasters. The Tower Drum technology minimizes heat loss by rotating stirring wings inside the vertical drum rather than rotating the drum itself.
-
Temperature Precision
By measuring not only the temperature inside the drum but also the drum itself, the S Series ensures accurate and consistent roasting environment from input to release.
Brain behind the perfect roast,
Roastware
-
“Beyond Human, For Human"
Spawned from the research of many dedicated engineers, chemists, and roasting professionals, the embedded Roastware is the brain of the S Series. -
Program Mode
You can select the bean’s origin, processing method, and desired roast level. Roastware will factor in all the information and automatically run optimized roast for you, allowing any level of roaster to produce high quality roast from the get-go.
-
Pre-heating
Pre-heat setting allows the roaster to set the temperature inside the drum and of the drum itself to ensure an ever-consistent roasting environment.
-
Manual Roasting Mode
Manual mode represents the S Series’ core value proposition. Immediate and precise control over convection and radiation heat allows you to define your roast like never before.
-
User Profile Mode
Save your favorite profile and replicate with unrivaled accuracy and consistency. Auto-replication on the User Profile Mode is the most distinguishing feature of the S Series, which can save you a lot of time and cost and increase productivity by multi-folds.
